# hidbus.4

`hidbus` — 通用 HID 总线驱动

## 名称

`hidbus`

## 概要

要将此驱动编译进内核，请在内核配置文件中加入以下行：

> device hidbus device hid

或者，要在引导时以模块方式加载该驱动，请在 loader.conf(5) 中加入以下行：

```sh
hidbus_load="YES"
```

## 描述

`hidbus` 驱动提供对单个 HID 传输后端附加多个 HID 驱动的支持。参见 [iichid(4)](/man/man4/iichid.4.md) 或 [usbhid(4)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man4/usbhid.4.md)。

每个 HID 设备可有多个组件，例如键盘和鼠标。这些组件使用不同的报告标识符（一个字节）组合成称为集合的组，以区分数据来自哪个组件。`hidbus` 驱动上附加了其他处理特定类型设备的驱动，`hidbus` 将数据广播给所有这些驱动。

## SYSCTL 变量

以下变量既是 [sysctl(8)](/man/man8/sysctl.8.md) 变量，也是 [loader(8)](/man/man8/loader.8.md) 可调参数：

**`hw.hid.hidbus.debug`** 调试输出级别，0 表示禁用调试，更大的值会增加调试消息的详细程度。默认值为 0。

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/hidbus.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
